IMPROVEMENT EN FLOWS.

Specification forming part of Letters Patent No. 3 F6955, dated April 9, 1561.

To all whom it may concern:

- Be it known that I, J osnrn B. COOPER, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Plow; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side view of my invention; Fig. 2, a back view of the same; Fig. 3,-a sec tion of a portion of the same, taken in the line a: 00, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain improvements in that class of plows which are designed for very general usethat is to say, those plows which may be adapted to perform various kinds of work, as turning a sod, loosening the subsoil, or performing the work of an ordinary shovel-plow or cultivator.

The invention consists, first, in a novel and improved mannerof applying a subsoil-share, whereby the same may, it is believed, operate in a better manner than those hitherto used, in consequence of a certain degree of self-adjust-ability which is allowed the former; second, in a novel arrangement of the landside and standards, whereby the former may be adjusted to suit various kinds of shares, which may be used for different kinds of work.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the beam of the plow, B B the handles, and O the handle brace or support. These parts may be of usual construction, and therefore do not require a minute description.

D-E are two standards, the lower parts of which are of curved form, and are connected together, the front standard, D, extending down rather farther than standard E, as shown by the dotted lines in Fig. 1. The front standard, D, is attached at its upper end permanently to the beam A by abolt, a, and the back standard, E, is attached to the beam A by a bolt, Z), which passes through an oblong slightly-curved slot c, in the upper part of said standard, the slot 0 admitting of the beam A being adj nsted on the bolt to as a center, so that the front end of the beam may be raised or lowered, as desired, according to the depth of the cut or furrow required. This will be fully understood by referring to Fig. 1.

When an ordinary turning-plow is required, the mold-board F is attached at its front part to the lower part of standard D by a strap, 61, and the back part of the mold-board is at tached to an arm or brace, G, which is connected at its inner end by a bolt, 6, to a metal strap, H, which is secured by a bolt, f, to the standard E, and has its upper part bent over in a horizontal position to receive the brace G, as shown clearly in Fig. 2.

I represents the landside, which may be of the usual form. This landside is attached to the standard E, near its junction with standard E, by a screw, and the back part of said landside is attached to the lower part of the strap H. When the mold-board F is used, the front end of the landside abuts against the share J of the mold-board, as shown in Fig. 1, but when an ordinary shovel-share is used the screw g is fitted in a hole, h, in the standard E back of the hole formerly used, (see dotted line, Fig. 1,) the strap H admitting of this adjustment in consequence of working on its bolt f. By this'adj ustinent of the landside the front part of the standard D is allowed to extend in front of the front edge of the landside, as shown in red, Fig. l, and is therefore left perfectly free or unencumbered for the attachment of a shovel-share, which is attached directly to the standard D.

K is a bar which is bolted to the standards D E in about a horizontal position, and has a curved standard or foot, L, attached to its back end by a bolt, 72, which passes through either of a series of holes, 1', in foot 11. The foot or standard L is allowed to work freely on the bolt t, and to the lower end of the foot a subsoil-share, M, is attached.

N is a curved or sector arm, the lower end of which is attached by a bolt,j, to the foot or standard L, just above the share M. The arm N is fitted in a loop or guide, 0, attached to bar K, and the upper part of said arm is perforated with a series of holes, 70, in either of which a pin, Z, is placed.

Vhen the implement is used as a subsoilplow and turning-plow combined, the moldboard F is employed, and the share M is adjusted a proper distance below the mold-board F by placing the bolts 2' and pin Z higher or lower in the foot and arm. The pin Z serves to retain the foot L and its share M under the action of the earth as the implement is drawn along, and in case the share M catches under a root or any obstruction it will, as the plow is drawn back naturally rise, and thereby greatly facilitate the extrication of the plow from the obstruction, the arm N passing up in the guide 0, and the share M passing between the landside and mold-board, as shown in red in Fig. 1. I

When the implement is used as a turningplow only, the pin 2 may be adjusted, so as to retain the share M in the position last inclicated.

Thus it will be seen that the plow constructed and arranged as described is capable of being adapted to various kinds of work.
